(2) Serial clock selection register 1n (CSIC1n)
Address: FF81H After reset: 00H R/W
CSIC10
Note
Symbol
This register specifies the timing of the data transmission/reception and sets the serial clock.
CSIC1n can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
